Synopsis:          Moderate: glibc security and bug fix update
Advisory ID:       RHSA-2021:3315-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://access.redhat.com/errata/RHSA-2021:3315
Issue date:        2021-08-31
CVE Names:         CVE-2020-10029 CVE-2020-29573 
=====================================================================

1. Summary:

An update for glibc is now available for Red Hat Enterprise Linux 7.6
Advanced Update Support, Red Hat Enterprise Linux 7.6 Telco Extended Update
Support, and Red Hat Enterprise Linux 7.6 Update Services for SAP
Solutions.

Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Server AUS (v. 7.6) - x86_64
Red Hat Enterprise Linux Server E4S (v. 7.6) - ppc64le, x86_64
Red Hat Enterprise Linux Server Optional AUS (v. 7.6) - x86_64
Red Hat Enterprise Linux Server Optional E4S (v. 7.6) - ppc64le, x86_64
Red Hat Enterprise Linux Server Optional TUS (v. 7.6) - x86_64
Red Hat Enterprise Linux Server TUS (v. 7.6) - x86_64

3. Description:

The glibc packages provide the standard C libraries (libc), POSIX thread
libraries (libpthread), standard math libraries (libm), and the name
service cache daemon (nscd) used by multiple programs on the system.
Without these libraries, the Linux system cannot function correctly.

Security Fix(es):

* glibc: stack corruption from crafted input in cosl, sinl, sincosl, and
tanl functions (CVE-2020-10029)

* glibc: stack-based buffer overflow if the input to any of the printf
family of functions is an 80-bit long double with a non-canonical bit
pattern (CVE-2020-29573)

For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.

Bug Fix(es):

* glibc: Adjust to rpm's find-debuginfo.sh changes, to keep stripping
binaries (BZ#1982317)

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

For the update to take effect, all services linked to the glibc library
must be restarted, or the system rebooted.

5. Bugs fixed (https://bugzilla.redhat.com/):

1810670 - CVE-2020-10029 glibc: stack corruption from crafted input in cosl, sinl, sincosl, and tanl functions
